Editing Loader (computing) (section)

==Dynamic linkers==
[[Dynamic linker|Dynamic linking loaders]] are another type of loader that load and link [[shared libraries]] (like [[Executable and Linkable Format|.so files]], [[dynamic link library|.dll files]] or .dylib files) to already loaded running programs.

Where such shared libraries can be shared by multiple processes, with only one single copy of the shared code possibly appearing at a different (virtual) address in each process's address space, the code in the shared library is required to be relocatable, ie the library must only use self-relative or code segment base-relative internal addresses throughout. Some processor have instructions that can use self-relative code-references in order to facilitate this.
